Winterization

Winterization

Winterization helps restore irrigation system efficiency by sanitation to prevent build-up and microbial growth while the system is not in use.  At Meras Water Solutions, we tailor each winterization program to your needs, depending on your water analysis, location, and symptoms.

Over time, mineral build-up and biofilm will lead to plugging or fouling, that can cause significant problems in your irrigation system. The winterization process is a single scrub maintenance application to rid irrigation plugging, while also maximizing the opportunity to restore irrigation system efficiency and distribution uniformity.

The winterization process is conducted during the last irrigations of the season after post-harvest fertilizers and nutrition are applied. Treated water flows through the irrigation system and cleans out the substances that have the potential to cause plugging and fouling. From the last irrigation of the previous season to the first irrigation of the next season, the treated water will remain in the irrigation line preventing the buildup of biofilm and other substances that may cause clogging. The contact time the treated water has in the irrigation system will ensure proper breakdown of potential foulants without causing harm to your system. The oxidizer used in a winterization process is broadly effective against microorganisms in breaking down to safe and inactive residues.

Before your next production season starts, a proper post winterization flush is required to evacuate the inactive mineral or residues, leaving a clean and sanitized irrigation system ready for the new season. A complete flush is comprised of three parts; filter back-flush, flushing main and sub-main lines, and flushing drip lines.

Filter Backflushing

Back-flushing your filters should be a regular activity as your filter’s performance depends on it.  Any accumulation of debris can reduce pressure and lower the water application rate (GPM) of your system. Flushing should release any accumulated particulate or organic matter and clear it from your system.

Flushing Main and Sub-Main Lines

The main, sub-main, and distribution lines in the system should be flushed in sequence. Each one of them should be flushed for at least two minutes or until the flushed water runs clear.

 Dripline Flushing

Dripline flushing will force evacuate the organic matter, mineral, or residues and will complete the winterization process. Flushing should be performed sequentially for a block in a single systematic flushing until the lines run clear.  Depending on your specific irrigation system, a good recommendation is to open up no more than 15 hose ends at a time to keep system pressures high enough to get a thorough flush.

Depending on your specific location and water source, It is recommended that an irrigation system flush should be performed periodically throughout the irrigation season to maintain proper uniformity.

Winterization will prepare you and your irrigation system for the future production seasons. For more information, contact An Ag Water Specialist from Meras Water Solutions to consult with you and go over any questions you may have about the winterization process. 

The State of The Almond Industry

The State of The Almond Industry

Almonds, its that time of year where everyone is shaking the “L” out of them. From Tehama County, all the way down the center of California to Kern County, California produces 100% of the United States’ almonds, while producing 80% of the worlds’ #1 superfood. With the start of harvest, I figured we could pay tribute to the tree nut and the effect it has had on the California economy.

In 2018, the almond industry hit a record in domestic shipments reaching 735 million pounds. The top producing counties, bearing the most almonds in 2017 were Kern, Fresno, Stanislaus, Merced, and Madera. These counties held 73% of California’s total bearing almond acreage. The almond industry in California provides 100,000 employment opportunities, 97,000 of them being in the central valley. As California is the leading producer of almonds in the world, Australia and the European Union are the leading foreign producers at 6 and 5 percent. With the majority of almonds being produced in California, in 2018, exports were made to more than 90 countries. Spain is the number one export market.

One thing that has always fascinated me about the California Almond industry is the commitment to sustainability. Majority of almond producers in California commit themselves to reduce the number of resources they use to produce their crop. Approximately 75% of Almond producers grow on 100 acres or less. Along with reducing land use, producers have made excellent strides in reducing water use as well. In the last 20 years, the industry has reduced how much water it takes to produce a pound of almonds by 33%. Almond producers have been able to achieve this through micro-irrigation and other water-saving technology practices. The Almond Board of California set a goal for producers to reduce the amount that it takes to produce one almond by 20% by the year 2025.

When it comes to the production of an almond, no part of the production goes to waste. The hull of the almond is used in many diets of species both big and small. Many livestock producers and insect farmers use the hulls as part of their feed for their stock. Shells are transformed into charcoal-like powders where they can be used in the production of recycled plastics. Even after production is over and the trees are ripped out, they are usually ground into small chips and diced into the soil to promote and improve organic matter in soil for future crops.

Adding $11 billion-dollar value to the California Gross State Product, almonds have made huge strides in the California economy. As healthier lifestyles are rising in popularity, the demand for almond production does as well. Thankfully, the industry continues to take actions in environmental responsibility and promotes it throughout the entire agriculture industry.

Food Safety: A Responsibility for Everyone

Food Safety: A Responsibility for Everyone

According to a recent article in California Ag Today, farmers can expect food safety inspections to be in their future. The Produce Safety Program, under the California Department of Food and Agriculture (CDFA), is working to have farmers comply with both the Food and Drug Administration (FDA) and CDFA produce safety rules through inspections of farms. Large operations with annual sales greater than $500,000, will be the first of the 20,000 farms to be inspected according to the produce safety rule. Inspections will not be unforeseen, and will only be done through set appointments. The goal of the Produce Safety Program is to “educate than regulate,” meaning both the FDA and CDFA want to inform producers about the legal compliances within food safety, then take action and implement them within the operations.

On September 10th, 2019 the FDA announced a cooperative agreement with the National Association of the State Departments of Agriculture (NASDA) toward the produce safety rule. This agreement is said, “to provide critical information and resources to help state and territorial regulatory agencies plan and help carry out the implementation of the Food Safety Modernization Act (FSMA) Produce Safety Rule.” The agreement will provide funding that will allow NASDA to help state and territorial produce safety regulatory programs to encourage safe production of crops, understand the Produce Safety Rule, and how to comply with the requirements of the rule. The overall goal of the 5-year cooperative agreement is to develop a nationally integrated food safety system, by ensuring consistency of produce safety programs with the Produce Safety Rule.

To help implement the compliances, NASDA will also host a National Consortium meeting including all state and territorial agencies to assist in their understanding of the new produce safety rule. The meeting will provide program updates, share the best practices, and the opportunity for feedback to the FDA for enhancements and program adjustments. Along with the National Consortium, NASDA will work closely with the FDA to prepare and implement the On-Farm Readiness Review system and develop national produce safety regulatory program that promotes a stable foundation of produce safety.

From the consumer to the producer, and the retailer to the government officials, everyone is a stakeholder in the mission to achieve proficient food safety. There is a common goal to prevent the outbreak of viruses caused by pathogens rather than suffer from the consequences. The consumer is responsible for washing their produce to provide safe and healthy food for their family and themselves. The retailer and processors are responsible for making sure produce is kept in a clean area and packaged for the safety of consumers. The government officials make sure all parts of the process are held at safe and healthy standards for all. The farmer is the very base of the triangle, whereas if it’s not clean produce from the beginning, it may cause a domino effect throughout the whole process. Attaining food safety is a team effort through the entire agriculture community. 

Van Groningen and Sons

In 2017, Van Groningen & Sons had a block of almonds where approximately 30% of the emitters where mostly or completely plugged due to biofouling. After conducting a dual-product remediation, the Distribution Uniformity test revealed an astonishing improvement!

In 2015, the ponds were covered with a blanket of Duckweed one to two inches thick…we met with Meras Water Solutions to develop a remediation plan…within a few months, the Duckweed was gone and the critical levels of oxygen in the ponds was improved.
